The Herring Research Group
The Herring research group at the University of Tennessee, Knoxville – also known as the Porous Media for Climate Solutions lab – investigates how we can leverage geologic porous media to limit climate change and enable a green energy transition. Our research looks at:
- Optimizing geologic carbon sequestration technologies
- Mitigating risks of leakage of subsurface carbon storage
- Enhancing engineered carbon mineralization
- The potential of underground hydrogen storage as a high-capacity energy storage technology
We conduct experiments utilizing 3D-4D characterization of porous media, multiphase fluid configurations, and dissolved constituent concentration fields.
